Homework Statement
Problem given basically in the beginning of the book, Sec. 1.4, about separable equations.
Find general solutions (implicit if necessary, explicit if convenient) of the diff. eq.
[tex]dy/dx+2xy^2=0[/tex]
Homework Equations
There was a previous section where they popped this out of thin air:
A solution of [tex]dy/dx=y^2[/tex] is [tex]y=1/c-x[/tex]
I'm presuming that that is supposed to be helpful somehow.
The Attempt at a Solution
[tex]dy/dx=-2xy^2 => dy/y^2=-2xdx[/tex]
Now I can't integrate the left side.
I'm sure that is an abysmal way of going at it. So any help would be appreciated.
